G. CHILSON, OF BOSTON, MASSACHUSETTS.

PARLOR-STOVE.

Specification of Letters Patent No. 7,436, dated June 18, 1850.

To all whom t may concern:

Be it known that I, GARDNER CHILsoN, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and useful Parlor-Stove,termed a Perfect Parlor-Stove;7 and that the following is a full, clear,and exact description of the principle or character which distinguishesit from all other things before known and of the usual manner of making,modifying, and using the same, reference being had to the accompanyingdrawing.

I have in this new construction for parlor stoves' endeavored to bringinto a graceful,

and perfect design, as many improvements in the economy of heat, and itsproper diffusion, as were required to form what its name indicates, aperfect parlor stove; which should at once prove a beautiful ornament,and great comfort; each part being especially adapted to the purposesintended, and the whole strictly harmonizing, with the beauty of thedesign. l

The parts are constructed as follows; first a broad, oblong base (a)with a deep molding, around its edges, forming a recess below, serves asthe foundation, upon which the other parts rest. At the center of thisbase, (a) I place the central portion of the stove, consisting first ofthe ash box (b), of oblong form, and curving upward from the base, in ahollow molding, and gradually contracting to a properl size, as clearlyshown in the drawing; in this the ash 'draw is situated, the front of ithaving the same curve, as the front of the ash box, and forming a partthereof. In this front there is a paneled damper, to admit a draft tothe fire. Abo-ve the ash box the lire pot (o), is situated, its formbeing similar to that of the ash box, reversed, which causes it toliare, and produces the best form for burning coal; and from the top ofthe tire pot, four straight plates stand up perpendicularly, forming thesides of a nearly cubical box (el). The front plate has a door (e), init, which instead of being hinged, slides upward and downward, and isheld at any desired elevation, by a. small catch ointed thereto, whichcatches into a rack made in the front plate. By this convenientarrangement, all the difficulty attending the employment of hinged doorsare obviated. This main body of the stove is surmo-unted by a to-p plateof very peculiar form, the central portion (f) of which, rises up like atruncated pyramid,

the sides of which are concaved. Around the ends, and back of the centerpart, the same plate, is formed by an upward projection into a flue (g),the curvature of the sides of which, are convex, as clearly shown in thedrawing. This portion of the plate projects out beyond the stove, oneither side and forms in connection with a bottom plate, a flue aroundthe back and two ends; the corners being curved at their junction, andshowing in the sectional plan a U form. At the center of the back ofthis flue, there is a rectangular one (71,), opening into it, thatextends down to the other flue (i), of similar form horizontally, asthat just described lettered (g) ;-but somewhat larger in dimension, andin its cross section a pointed arch. At the two ends of this flue, thereare two lozenge shaped prisms, forming connecting pipes (7c), betweenthe lower flue (i), and the upper one (g).

The rear rectangular pipe (h), has an opening at (L), into the firechamber, and just above it, a valve (m), that when shut closes the wholearea of the pipe above the f opening, and causes the products ofcombustion to descend into the flue (i), around *which it courses ineach direction, to the,

front when it ascends the pipes (s), to the upper horizontal flue, andthence returns to the first named pipe (71,); from which it escapesthrough an exit pipe, at (h2). This exit pipe is made to move, up anddown like the one, for which I have applied -for patent, in an open fireplace. Of course when the valve (m), is open, the smoke passes offdirect, otherwise it causes the heat to descend to the most usefulpoint, and heat a iue near the floor, thus greatly economizing fuel.

I admit air in under the base, either from t-he apartment, or some placeexterior to it, from whence it rises up through openings (n), on eachside between `the ash box, and lower flue (i), a very effective mode ofcarrying oft1 the heat from the sides, and disseminate it through theapartment. It will be observed that in this construction, each of theiues is separate from, and independent of, the main body of the stove,in which it materially differs from other stoves, with descending flues,especially in the horizontal fiues, which are ordinarily in one piece,with the base and capital of the stove. To clean out the ashes, from thelower horizontal pipe, Vit is necessary to have openings therein, whichI locate in the front ends, and Y The arrangement of the flues incombinaclose With doors (w, so placed in front tion With the re chamber,substantially in of the ascending pipe, as to prevent any the manner,and for the purposes set forth. 10
